People in Demon Slayer: The Journey That Began with Demon Slayer

The older sister bit her lip, her mind already made up: "No, I still want to follow that gentleman. I believe that every ghost is different, and I want to slay those evil ghosts who do all sorts of wicked things!"

The older sister looked at her younger sister with unwavering determination: "Shinobu, do you want to come with me?"

The younger sister wiped away her tears and said, "Yes! I want to stay with my older sister forever!"

The two sisters caught up with Yosuke once again. Yosuke looked at the two sisters, his heart filled with helplessness: "Even if I am a ghost, will you still choose to follow me?"

"We are prepared. We will not be swayed by hatred. We choose to slay evil spirits in order to protect the happiness of others!"

Yosuke remained silent for a moment. The next ten years or so would be a vacuum period, and Kibuy Muzan would not appear until he saw Kamado Nezuko's ability to withstand sunlight.

Given Muzan Kibutsuji's cautious and timid nature, even if he were to kill everyone who knew about the Breath of the Sun, he would not be completely at ease.

Unless Kibuy Muzan is also immune to sunlight and becomes an ultimate being, he will not reappear in the public eye. Until then, Kibuy Muzan dares not take any risks.

When that time comes, the first thing Kibuyaku Muzan will probably do is kill him.

After all... this world doesn't need two ghost kings.

Especially the self that had always wanted to kill it.

The gap of more than ten years should have been enough to teach the two sisters.

Yosuke looked at the two sisters: "I hope you won't regret your choice in the future. Since that's the case, you can stay by my side and learn for now. I will teach you the breathing techniques of human demon slayers. After you've learned them, you can decide for yourselves whether to stay or leave."

The two sisters knelt on the ground, tears streaming down their faces, and bowed in a gesture of respect, saying, "Thank you, Master."

"Work hard. Now that you've made this choice, there's no turning back. What are your names, sisters?"

"Kanae Butterfly".

"Shinobu Kocho".

Yosuke: ...

Yosuke rubbed his temples. Is the world really that small?

Osamu and Koyuki, Gyutaro and Koume, and now Kanae and Shinobu.

Yosuke silently reminded himself: I'm used to it, I'm used to it. I've already endured the two future Twelve Demon Moons, so what's the difference between two future Demon Slayer Corps Pillars?

Yosuke turned around, took a deep breath, and said, "Let's go."

Kanae and Shinobu followed Yosuke on either side, embarking on another journey toward an unknown future.

Chapter 37 Nichirin Blade

Yosuke chose different teaching methods for the Butterfly Sisters.

After all, human lifespans are different from those of demons, so a more relaxed approach can be taken towards Osamu and Gyutaro.

But the butterfly sisters are different. Humans only have a few years of golden learning time, and how much knowledge they can acquire during that time determines their future potential.

The two butterfly sisters are currently eleven and nine years old, respectively, which is the golden age for their learning. Therefore, Yosuke wants to personally teach them as much as possible during this prime learning period.

In order to better teach the Butterfly Sisters, Yosuke gave up his nomadic life and chose to settle down in a small village.

Since I promised them, I have to take responsibility for it.

inside the house.

"Breathing techniques are a skill used by human demon-slaying swordsmen to enhance their physical abilities in order to fight demons whose physical abilities far surpass those of humans. Its main function is to strengthen the heart and lungs, thereby allowing the blood to absorb a large amount of oxygen in a short period of time, which can instantly increase physical abilities and temporarily give them physical strength comparable to that of demons."

Kanae and Shinobu took out their notebooks and began writing something down with serious expressions.

Yang Jie asked in confusion, "What are you writing down?"

"I think what my master said was very profound, so I want to write it down and study it repeatedly."

"There's no need to take notes. I'm just introducing you to breathing techniques. The most important thing is for your bodies to remember them, rather than for you to take notes."

The Butterfly Sisters were so serious that they almost made Yosuke lose his mind. He remembered how he had once impulsively decided to teach Osamu and Gyutaro.

...It's hard to put into words.

Since then, Yosuke has adopted a laissez-faire approach towards Osamu and Gyutaro.

“You will start by training in the most basic breathing techniques. Once you can master your breathing, you will have entered the first stage. At that time, I will teach you water breathing.”

With Yosuke's instructions, the Butterfly Sisters were full of energy and put all their effort into training their breathing techniques.

As night fell, Yosuke went outside. He already had a plan in mind for the teachings he would give to Kanae and Shinobu.

In the future, Kanae Kocho will develop Flower Breathing from Water Breathing, and Shinobu Kocho will develop Insect Breathing from Flower Breathing. All I need to do is teach them Water Breathing step by step.

However, the most important thing for a demon-slaying swordsman is to have a Nichirin Blade.

Yosuke's Nichirin Blade was abandoned on the battlefield during the siege of Muzan. Now, he is going to prepare two Nichirin Blades for the Butterfly Sisters to learn the sword form of the Breathing Technique.

In the pitch-black night sky, a crow with scarlet eyes flew by.

The demon crow landed on Yosuke's shoulder, and Yosuke read the demon crow's memories.

Yosuke chuckled slightly, muttering to himself, "Did I find it...?"

The demon crow flew away, and Yosuke spread his blood-red wings and followed it into a forest.

In the woods, a Demon Slayer Corps was struggling against a demon.

Breathing techniques are the most basic skills for Demon Slayer Corps members, but the sword techniques that accompany them are not all that ordinary Demon Slayer Corps members can learn.

Although all sword forms of the Demon Slayer Corps' Breathing Techniques are open, a Demon Slayer Corps member with average talent may only be able to learn one sword form in their entire life.

Those with exceptional talent will become the stepsons of a Pillar, receiving the Pillar's full guidance and becoming candidates for the next Pillar.

Yosuke, who was silently observing the battle, discovered that the current members of the Demon Slayer Corps were much stronger than those led by Naosai Ubuyashiki hundreds of years ago.

Back then, the Breathing Techniques were just becoming popular in the Demon Slayer Corps. Not to mention the sword forms of the Breathing Techniques, not many people had even mastered the Breathing Techniques themselves.

To become a full member of the Demon Slayer Corps, learning Breathing Techniques is the most basic requirement; otherwise, one can only serve in the Corps' logistics unit.

However, the demons ravaging the human world now are different from those of the past. The demons created by Kibu and Muzan, who have completely concealed their whereabouts, are much stronger than before.

Just like the demon in front of Yosuke now, facing an entire team of Demon Slayers, he not only handles them with ease, but even toys with the Demon Slayers members.

The battle was nearing its end, and the demons were gradually losing patience, intending to kill the members of the Demon Slayer Corps.

Yosuke flapped the blood-red wings on his back and descended from the sky, causing cracks to appear in the ground beneath his feet upon landing.

Yosuke unleashed his full power as the Demon King.

The Demon Slayer Corps members behind Yosuke stared wide-eyed at him in despair: "How... how could a demon of this level appear?"

Not only the Demon Slayer Corps, but even the demons were stunned into place by Yosuke's aura as a demon king.

Yosuke turned and walked toward the Demon Slayer Corps members behind him. The Demon Slayer Corps members' hands, which were gripping their Nichirin Blades, trembled uncontrollably.

Yosuke gradually approached the two Demon Slayer Corps members closest to him, but these two members had lost even the courage to swing their swords. They stared blankly at Yosuke without making any move.

Yosuke took the two Nichirin Blades from their hands. The Demon Slayer Corps members whose Nichirin Blades were taken slumped to the ground, their minds blank, forgetting even to breathe, with large beads of sweat dripping down their cheeks.

Yosuke didn't offer any explanation for the Demon Slayer Corps members' fear, but instead said softly, "As payment, I will help you slay the demons."

Before the Demon Slayer Corps members could react, Yosuke had already vanished from his spot and instantly appeared behind the demon.

The demon clutched its neck and looked at Yosuke in disbelief.

Yosuke flicked his Nichirin Blade, shaking off the demon blood clinging to it.

"Aren't we the same kind? Why kill yourself?" The demon was filled with doubt as its body gradually turned to ashes and disappeared on the spot.

Having obtained the Nichirin Blade he desired, Yosuke once again flapped his blood wings, soared into the sky, and disappeared into the horizon.

The members of the Demon Slayer Corps were panting heavily. If the demon in front of them hadn't disappeared, they might have thought it was all a dream.

The Demon Slayer Corps members reported Yosuke's appearance and his slaying of the demon to Hiya Ubuyashiki.

When Ubuyashiki Hiya learned of this, he didn't care. Instead, he guessed Yosuke's intention in taking the two Nichirin Blades and was overjoyed.

Ubuyashiki Hiya opened a wooden box, inside which was a Nichirin Blade with nicks and chips on its blade—the very Nichirin Blade that Yosuke had abandoned on the battlefield.

"It seems that our ancestors have also found a successor to the Breathing Technique."

Chapter 38 Cultivation

Back inside, Yosuke found that the Butterfly Sisters were still awake, their faces flushed as they practiced their breathing techniques.

Why aren't you all asleep yet?

Shinobu Kocho said eagerly, "My sister and I want to become stronger quickly!"

“Cultivation is not a one-time thing; you must know how to balance work and rest. Only by resting well can you have the energy to cultivate better the next day.”

At Yosuke's request, Kanae and Shinobu lay down on the bed. Yosuke blew out the candles, and the brightly lit room instantly went dark.

After the night their parents were attacked by evil spirits and tragically killed, Kanae and Shinobu developed a fear of the dark and couldn't fall asleep for a long time.

Shinobu's voice trembled slightly: "Master, are you still there?"

"Sleep peacefully, I'm always here..."

Hearing Yosuke's voice, the Butterfly sisters were relieved and gradually drifted off to sleep.

Yosuke leaned against the window, listening to the calls of the Butterfly Sisters beside him, gazing at the moon in the sky.

I wonder how they are doing now...

For several days in a row, the butterfly sisters would wake up as soon as it was light and begin practicing their breathing techniques.

Because they cannot be exposed to sunlight, Yosuke can only guide their training through the house.

The butterfly sisters were quite talented; in just half a month, they had mastered the basic breathing technique.

Their physical abilities were also enhanced. When the time was right, Yosuke handed them two Nichirin Blades and instructed them on the Water Breathing technique and the corresponding sword forms.

Spring passed and autumn came; two years went by.

Kanae and Shinobu have grown into beautiful young women.

The two butterfly sisters gradually emerged from the shadow of the demon attack that day.

Kanae Butterfly now often wears a smile on her face. She is very gentle and also very talented, having dabbled in guzheng, flower arrangement, and tea ceremony.

The outside was filled with flowers, and even the inside was filled with flowers planted by Kanae Butterfly.
